Abstract

Claims (15)

1 . An instillation and negative pressure wound therapy apparatus comprising:

an instillation and exudate unit comprising:

a body defining a wound fluid collection canister configured to collect wound exudate and defining a pump head formed by a partially cylindrical recess in a wall of the body;

a flexible fluid instillation conduit extending along the pump head and configured to be compressed by a pump rotor, the flexible fluid instillation conduit having a first end coupled to a first port formed by the wall and a second end coupled to a second port formed by the wall, the first port and the second port on opposing sides of the partially cylindrical recess in the wall;

a first conduit disposed on an interior of the body and configured to be fluidly coupled on one end of the first conduit to a negative pressure source and on another end to a wound site;

a second conduit disposed on the body and having one end of the second conduit communicating with the wound fluid collection canister and on a second end to a wound site; and

a third conduit disposed on the body and fluidly coupled to the flexible fluid instillation conduit through the first port;

a negative pressure wound therapy unit coupled to the instillation and exudate unit,

the negative pressure wound therapy unit further comprising:

a peristaltic pump configured to pump instillation fluid through the third conduit and configured to compress the flexible fluid instillation conduit.

2 . The apparatus of claim 1 , further comprising: a port disposed on the wound fluid collection canister and configured to allow exudate to drain from the wound fluid collection canister.
